How should I be treating my hardwood floors?

I know there’s differing opinions on this, particularly on the Murphy’s Oil front, but I need some advice.

My house was built in 1928 and remodeled (electrical, ugly-ass bathrooms) about ten years ago. Hardwoods except in two rooms, the hall, the kitchen and bath. I don’t know what the finish is on the floors and if they were refinished in the remodel. When I moved in my mom Murphy’s Oiled the floors (which are in decent shape but would look really great if they were refinished) and they looked much improved.

Now they need some sort of cleaning/finish. What should I use? Murphy’s? And can I just go around the rugs? How to apply, etc? (I ain’t moving no furniture and that’s that.)

I always use Bona hardwood floor cleaner. It’s easy and works very well.

I move rugs but not furniture. A cleaning lady does the difficult bits every once in a while.

Vacuum first using one that’s appropriate for hardwood- like a Miele.
